How Can Go's 'Foreign Function Interface' Be Used to Call C Functions?

Utilizing Go's "Foreign Function Interface" for C Function Invocation

Go provides a mechanism known as the "foreign function interface" (FFI), which enables the invocation of C functions from Go code. This capability proves immensely valuable in situations where it becomes necessary to interact with existing C libraries or legacy APIs from within a Go program.

To leverage the FFI, refer to the illustrative file located within the Go repository at [this link](https://github.com/golang/go/blob/master/src/syscall/dll_windows.go). This file aptly demonstrates how to effectively encapsulate a C library within a Go wrapper. Detailed comments accompanying the code expound on each step of the implementation.
